This is the "Modern Monolith" of the collection. While the 24x24 format is a traditional square, the 18x36 Calacatta Gold Tile introduces a contemporary, architectural "plank" ratio. It is the premier choice for a "Metropolitan Penthouse" or "Sleek Gallery" aesthetic, prioritizing elongated stone faces that create fewer grout lines and a more expansive, streamlined "slab look" on both floors and walls.

PRODUCT TITLE

Grand Series: Calacatta Gold 18" x 36" (A-Grade) Polished Italian Marble Tile

PRODUCT DESCRIPTION

Transform your environment into a sanctuary of high-end design with the A-Grade Calacatta Gold 18x36. Sourced from the premier strata of the Apuan Alps, this large-format tile is a masterclass in scale and proportion. The A-Gradeselection ensures a high-clarity white background with the classic, sophisticated interplay of smoky grey and the legendary "Gold" honey-toned veining.

The 18x36 format is a designer favorite for its ability to "stretch" a room. When laid horizontally, it makes narrow spaces feel significantly wider; when laid vertically, it adds staggering height to shower walls and foyers. The high-polished finish serves as a reflective canvas, magnifying the organic mineral "art" that flows across each oversized tile. This is the ultimate alternative to full slabs, offering the same majestic impact with the versatility of a modular tile system.

KEY FEATURES

• Modern 1:2 Aspect Ratio: The 18" x 36" dimensions offer a sleeker, more contemporary silhouette than standard square tiles.

• A-Grade Italian Selection: Hand-picked to ensure a clean white field and a balanced distribution of gold and grey veining.

• Slab-Effect Minimalism: Large dimensions mean significantly fewer grout joints, resulting in a cleaner, more monolithic surface.

• Precision Rectified Edges: Allows for ultra-thin grout lines (1/16"), further enhancing the "continuous stone" aesthetic.

• Versatile Application: Equally stunning as a seamless floor or as a dramatic floor-to-ceiling wall feature.

SPECIFICATIONS

INSTALLATION REQUIREMENTS

⚠️ CRITICAL: Large-format 18x36 marble is exceptionally heavy and sensitive to mortar color. You mustuse a High-Bond, Polymer-Modified Large Format Floor (LFF) White Thin-set. Using gray mortar will result in "ghosting," where the dark mortar color bleeds through the translucent white stone, permanently dulling its brilliance.

Manufacturer Recommendations:

• Recommended Grout: Use a High-Performance Non-Sanded Grout in "Avalanche" or "Warm Sand." A 1/16" joint is highly recommended to maintain the architectural flow.

• Leveling System: The use of a Lippage Control System (clips and wedges) is mandatory for this size. Large tiles are prone to "bowing" during the curing process; a leveling system ensures a perfectly flat, professional finish.

• Substrate Flatness: The floor or wall must be flat within 1/8" over 10 feet. Any imperfections in the substrate will cause these large tiles to "teeter" or crack.

FREQUENTLY ASKED QUESTIONS

• Can I use this on a shower wall? Yes, it is one of the most prestigious choices for a master shower. It creates a "hotel-spa" look with minimal maintenance due to fewer grout lines.

• How do I clean such a large surface? Use a pH-neutral stone soap and a microfiber mop. Avoid any acidic cleaners, as etching on a tile this large is very noticeable.

• How much variation should I expect? Being A-Grade, the background will be consistently white, but the veining is 100% natural. Some tiles may have bold gold strokes, while others feature softer grey wisps.

PRO INSTALLATION TIPS

• The "Horizontal Stretch": In a hallway or narrow bathroom, lay the 36-inch side perpendicular to the longest wall to visually push the walls out and make the space feel larger.

• 1/3 Offset Rule: If you are not doing a "stack bond" (aligned) layout, never exceed a 1/3 offset (stagger). A 50% "brick" offset can emphasize the slight natural "crown" or bow common in large-format stone.

• Back-Buttering is Key: Always "back-butter" the entire back of the 18x36 tile with a thin layer of white thin-set to ensure a 100% bond and prevent hollow spots.
